I would also like to add that your breed descriptions are spot on. She is a yes dog devoted to her people, she has no interest in straying,( although I would not let her) when I do allow her to go off leash she sticks to me pretty close. It is also true ( Dogo ) that when she is committed it is very hard to get her off or out of that state.I have learned to read the signs when she was around my other dogs as she is possessive and protective of me in particular. I do not live in a rural area but I could see these traits coming in handy protecting livestock against predators ie; cougars, bears, coyotes and stray dogs. I have noticed on the website that some of the dogs seem more laid back than others and I will probably try to get one of those pups.
